Determine if the dynamics in each of the following systems is (a) homogenous in time, (b)

homogenous in space, and (c) isotropic. Thus identify conservations laws. Explain your

reasoning clearly.

A ball bouncing elastically off a horizontal floor, a ball bouncing elastically off a speed hump, a

puck sliding on the floor of a compartment of a rotating ferris wheel(Ignore friction), a spherical

pendulum.
